고농도 슬러지 이송용 자흡식 진공강 펌프{A Vacium Self-priming Pump}{A Vacium Self-priming Pump}

본 발명은 축산 시설의 폐수슬러지, 하수슬러지, 오일슬러지를 비롯하여 식품공장에서 발생하는 식품폐기물 슬러지와 같이 농도가 진한 슬러지를 이송시키기 위한 자흡식 진공강 펌프에 관한 것으로 보다 구체적인 것은, 원통형으로 되어 외주면에 흡입구와 배출구가 배치되는 펌프실내에 200~300RPM 으로 회전하고, 원판형상으로 되는 회전원판을 배치하여 회전원판 외주를 따라 2~4개의 반원형돌기를 등간격에 형성하여 반원형돌기의 돌출단이 펌프실 원주내면에 접촉하여 회전되게 함으로써, 펌프실에 슬러지 유입부와 배출부가 진공강 관로가 형성되어 슬러지 이송이 원활하게 되는 자흡식 진공강 펌프를 제공한다.The present invention relates to a self-priming vacuum steel pump for transferring thick sludge such as food waste sludge generated in food factories, including wastewater sludge, sewage sludge, and oil sludge of livestock facilities. It rotates at 200~300RPM in the pump room where the inlet and outlet are placed in the pump room, and 2~4 semi-circular protrusions are formed at equal intervals along the outer circumference of the rotating disc by arranging a disc-shaped rotating disc so that the protruding end of the semi-circular protrusion is located in the pump room. Provided is a self-priming vacuum steel pump in which a vacuum steel pipe is formed in the sludge inlet and outlet in the pump chamber to facilitate sludge transfer by contacting the inner circumferential surface to rotate.

종래의 자흡식 진공강 펌프는 펌프실의 중심부에 회전원판을 배치하고, 회전원판 표면에 중심에서 원주방향으로 배치되는 바람개비 형상의 돌조를 일정높이로 형성한 임펠러를 배치하여 돌조 외면에 흡입구와 배출구를 형성하는 구성이기 때문에 임펠러를 고속으로 회전시켜 흡입로와 배출로를 형성해야 하므로 저항이 커지게 되고, 회전축의 베어링 마모가 심하게 일어나 베어링 수명이 짧아지는 불편이 있고, 진공강 형성이 미흡하여 펌프 가동단계에서 마중물을 투입해야 하는 등의 불편이 있었다.In the conventional self-priming vacuum steel pump, a rotating disk is placed in the center of the pump chamber, and an impeller formed with a pinwheel-shaped protrusion disposed in the circumferential direction from the center on the surface of the rotating disk is arranged at a certain height, so that the suction port and the outlet port are provided on the outer surface of the protrusion. Since the impeller must be rotated at high speed to form the suction path and the discharge path, the resistance increases, the bearing wear of the rotating shaft becomes severe and the bearing life is shortened, and the vacuum steel is insufficient to operate the pump. There were inconveniences such as having to put priming water in the step.

본 발명은 원통형상으로 되는 펌프실과 기어장치실이 전후로 배치되어 구획판으로 구획되고, 펌프실과 기어장치실의 일측방에 펌프실과 기어장치실의 직경보다 직경이 적으면서 펌프실과 기어장치실에 각각 연통하는 구획실을 형성하여 펌프장치실과 기어장치실 및 구획실의 개방부에 덮개를 씌워 체결볼트로 착탈가능케 체결하고, 펌프실에는 외주연부를 따라 상측과 하측에 펌프실과 연통하게 흡입구와 배출구를 형성하여 흡입호스와 배출호스를 연결하고, 펌프실에는 펌프실의 두께에 대응하는 두께를 가지는 원판형상으로 되어 내면과 외면이 펌프실의 내면과 외면에 대면하고, 외주면에 2~4개의 반원형돌기가 등간격에 형성된 회전원판을 배치하여 중심부의 회전축이 펌프실의 덮개중심부와 구획판중심부에 형성된 축잡이에 결합하여 베어링으로 지지되어 제자리회전되게 하고, 펌프실의 측방에 배치한 구획실에는 외주에 회전원판의 반원형돌기와, 결합하는 반원형의 요입홈이 형성된 구동원판을 배치하여 구동원판의 중심축을 구획벽을 통해 기어장치실의 구획실로 돌출시켜 기어장치실에 장치된 구동기어와 결합하여 피동하는 전달기어의 중심공에 결합하며, 구동기어 회전축은 덮개 외측으로 돌출시켜 전동모터의 구동축에 커플러로 결합하고, 펌프실의 주벽에 구멍을 뚫고, 기어장치실의 덮개에 구멍을 뚫어 연결관을 연결한 다음, 연결관에 개폐밸브를 장치함으로써, 기어장치실에 모이는 물을 펌프실로 흡수이동시켜 배출구로 배출시킬 수 있게 한 구성이다.In the present invention, the pump chamber and the gear chamber having a cylindrical shape are arranged in front and rear and partitioned by a partition plate, and the diameter of the pump chamber and the gear chamber is smaller than the diameter of the pump chamber and the gear chamber on one side of the pump chamber and the gear chamber, respectively. By forming a communicating compartment, the pump unit room, gear unit room, and the opening of the compartment are covered with a cover so that it can be detachably fastened with a fastening bolt. The hose and discharge hose are connected, and the pump chamber has a disk shape having a thickness corresponding to the thickness of the pump chamber, and the inner and outer surfaces face the inner and outer surfaces of the pump chamber, and 2 to 4 semi-circular projections are formed at equal intervals on the outer peripheral surface. By arranging the disk, the rotating shaft of the center is coupled to the shaft holder formed in the center of the cover and the center of the partition plate of the pump room, and is supported by a bearing to rotate in place. By arranging a driving disk having a semi-circular concave groove, the central axis of the driving disk is projected into the compartment of the gear unit through the partition wall, and it is coupled with the driving gear installed in the gear unit and coupled to the central hole of the driven transmission gear, The rotating shaft of the driving gear protrudes outside the cover and is coupled to the drive shaft of the electric motor by a coupler, drills a hole in the main wall of the pump room, drills a hole in the cover of the gear unit room, connects a connecting pipe, and then installs an on/off valve in the connecting pipe By doing so, the water collected in the gear unit chamber is absorbed and moved to the pump chamber so that it can be discharged to the outlet.

한편, 본 발명은 펌프실에 배치되는 회전원판과 구동원판은 중심부에 금속제 심판을 매설하여 그 외면에 합성고무를 일정두께로 피복하여 일체가 되게 구성하고, 펌프실과 기어장치실의 개방부 주벽과 덮개가 접촉하는 접촉면에는 실리콘 패킹이 개입되어 덮개가 부착되는 개방부를 실링할 수 있게 구성된다.On the other hand, in the present invention, the rotating disk and the driving disk disposed in the pump chamber are configured to be integrated by embedding a metal refrigeration in the center and coating the outer surface with synthetic rubber to a certain thickness, and the opening peripheral wall and cover of the pump chamber and the gear apparatus chamber Silicone packing is interposed in the contact surface to be in contact with and is configured to seal the opening to which the cover is attached.

이와 같이 된 본 발명은 전동모터를 작동시켜 구동기어를 회전시키면, 구동기어에 접촉하는 전달기어가 피동되어 펌프실의 구획실에 배치된 구동원판이 피동되고, 구동원판이 피동되면 펌프실에 장치된 회전원판을 회전시키게 되므로, 펌프실의 흡입구로 흡입된 슬러지를 회전원판 외주면에 형성 반원형 돌기가 밀어서 배출구 방향으로 강제 이동시켜 배출시키게 되므로, 펌프실 내주면에 회전원판의 회전방향을 따라 슬러지 이동관로가 형성되어 진공강이 형성되고, 이로인해 슬러지의 흡입과 배출이 원활하게 이루어지게 되며, 구동원판과 회전원판은 반원형 돌기가 구동원판의 반원형요입홈에 결합하여 피동되고, 외주면이 서로 밀착하므로 배출구와 구획실 사이가 구획되어 안전한 배출로를 형성하게 되는 것이다.In the present invention as described above, when the driving gear is rotated by operating the electric motor, the transmission gear in contact with the driving gear is driven to drive the drive disk disposed in the compartment of the pump room, and when the drive disk is driven, the rotating disk installed in the pump room Because the sludge sucked into the suction port of the pump chamber is formed on the outer circumferential surface of the rotating disc, the semi-circular protrusion is pushed and forced to move in the direction of the outlet to be discharged. is formed, so that suction and discharge of sludge are smoothly performed, and the driving disk and the rotating disk are driven with semi-circular projections coupled to the semi-circular indentation grooves of the drive disk, and the outer circumferential surfaces are in close contact with each other, so that there is a partition between the outlet and the compartment This will form a safe discharge route.

또, 슬러지에 함유된 수분이 구동원판 회전축을 통해 적은량이 누출되어 기어장치실에 모인다해도 모아진 물이 일정량이 되면 연결호스에 작용하는 흡인력으로 연결호스를 통해 기어장치실에서 펌프실로 흡인되어 배출구로 배출되어 슬러지와 함께 배출처리되기 때문에 기어장치실에 모이는 수분을 자동적으로 배출시킬 수 있고, 본 발명은 흡입과 배출이 이루어지는 경로가 진공강으로 형성되어 흡인력과 배출력이 강력하게 되므로 고농도의 슬러지를 원활하게 이송시킬 수 있는 이점을 얻을 수 있다.In addition, even if a small amount of moisture contained in the sludge leaks through the drive disk rotating shaft and collects in the gear unit room, when the collected water becomes a certain amount, it is sucked from the gear unit room to the pump chamber through the connecting hose with the suction force acting on the connecting hose and goes to the outlet. Since it is discharged and treated together with the sludge, the moisture collected in the gear unit chamber can be automatically discharged, and in the present invention, the suction and discharge path is formed of vacuum steel, and the suction and discharge power are strong, so that the high concentration of sludge can be removed. The advantage of being able to transfer smoothly can be obtained.

또한, 본 발명은 회전원판과 구동원판은 중심부에 금속제 심판이 매설되고, 그 외주에 합성고무가 피복되어 일체로 되는 구성이므로, 판체가 견고하여 형상유지가 확고하고, 표면이 합성고무로 되어 탄력성 있는 표면을 형성하므로, 회전원판의 외주반원형돌기가 펌프실 내주면에 접촉회전할 때, 탄력성과 유연성을 발휘하므로 펌프실 내주면과 반원형돌기의 밀착으로 이송관로의 누출을 막을 수 있어 슬러지 이송을 완벽하게 하므로 배출성능을 높일 수 있는 이점을 얻을 수 있고, 회전원판과 구동원판의 표면부식이 방지되므로 내구성을 발휘하는 이점이 있고, 고장발생율이 적으며 마중물 사용 필요성이 없는 진공펌프를 얻을 수 있는 이점이 있다.In addition, in the present invention, since the rotating disk and the driving disk have a metal plate embedded in the center and a synthetic rubber coated on the outer periphery of the present invention, the plate body is solid to maintain the shape firmly, and the surface is made of synthetic rubber for elasticity When the outer semi-circular protrusion of the rotating disc rotates in contact with the inner circumferential surface of the pump room, elasticity and flexibility are exhibited, so that leakage of the conveying pipe can be prevented by close contact of the inner circumferential surface of the pump room and the semi-circular protrusion, and the sludge is transported perfectly. There is an advantage that the performance can be improved, the surface corrosion of the rotating disk and the driving disk is prevented, so there is an advantage of exhibiting durability, and there is an advantage of obtaining a vacuum pump having a low failure rate and no need to use a priming material.
